The world teaches birth control. Tragically, many of our sisters subscribe to its pills and practices when they could easily provide earthly tabernacles for more of our Father's children. We know that every spirit assigned to this earth will come, whether through us or someone else. There are couples in the Church who think they are getting along just fine with their limited families but who will someday suffer the pains of remorse when they meet the spirits that might have been part of their posterity.
Ezra Taft Benson (1974). “God, family, country: our three great loyalties”
